While spreading the word on his new movie, John was asked to reflect on his best memory of the late Robin Williams.

“Well, it was wonderful to work with Robin on a film, but the best memories came earlier, when we were at Paramount together, hanging out. One time he came up to Santa Barbara to visit me and we were sitting in the lobby of a hotel. There was this big wedding going on next door, and we are getting a little bored, sitting there with our iced teas. I say, ‘Should we?’ and he said, ‘I think we have to.’ And we just crashed this wedding together. It was an all black wedding that just beckoned us and we just had a blast. We laughed about it for years because it was so unexpected and so much fun to just do that kind of impromptu thing,” John shared to Deadline.
